> 2. It actually is North Korea. We've been led to believe that they exist in a technological dark ages of sorts, with most of their infrastructure relying on technology that would horrify the average HN user. They're certainly belligerent enough, but now suddenly we find that they have not just the technology to pull it off, but also the talent? How does that kind of talent even develop under a strictly regimented government like North Korea's? What kind of ability do they actually have?

See, this really isn't the case, and why most people believe this is beyond me, when a google search would suffice. I'm not criticizing you, actually, just pointing out that there's an incredible amount of misinformation out there about North Korea. Look at these photographs of a technology trade fair in Pyongyang this summer, for example:

Most telling, IMO, is that a 32G usb is being sold for USD20, where at the time of writing, the same product was nearly USD16 on Amazon US. That's a remarkably low markup for a product, especially for one in North Korea. Also considering that it's a high volume, low price product with so little of a markup makes me think that other technologies must be very available and accessible, and that NK is hardly the technological dark ages that popular discussion has us think it is.

Of course, this all isn't to say that NK performed the hack, but I hardly think that a lack of infrastructure would really be the barrier if North Korea really wanted to train a cadre of hackers.
